Abstract
In some embodiments, a self-aligned electrospray device can include a silicon wafer, a fluid reservoir, and a circuit. The silicon wafer can have a layer of electrically insulating material deposited on a top surface and a deposited layer of electrically conducting material. The silicon wafer and the deposited layers can have through holes. The electrically insulating layer may be undercut. The fluid reservoir can be mounted to a bottom surface of the silicon wafer for containing fluid. The circuit can provide an electric potential difference and be coupled between the layer of electrically conducting material and the fluid reservoir.
